Astera Labs Tech Stack

AI infrastructure connectivity chips for hyperscale data centers

Semiconductor Manufacturing Santa Clara, CA 501–1,000 employees Founded 2017 Public Company

Astera Labs designs custom semiconductor connectivity solutions (CXL, Ethernet, NVLink, PCIe) for hyperscaler AI deployments. The hiring composition—145 engineering roles across principal, senior, and lead levels, with only 4 sales headcount—reflects a deeply technical, R&D-driven organization building custom silicon. Active projects span chip design, validation automation, and fabric switch development, while pain points cluster around validation complexity and power/performance robustness—typical of companies scaling from standards-based designs (PCIe, Ethernet) toward proprietary ASICs for cloud AI infrastructure.
